` a claims. (Cl. 122-19) without removing the boiler; a safeand economicheater that will give years of service; a thermo- .static lcontrol forthev burner and the pilot light for the latter which requires nowaterpressure;

for breaking up the` gas-more evenly by a free supplyiof air to'and onthe passage of the gas to its-point of consumption thereby'resulting ina ne vblue llame; for automatically igniting the a pilot light by anelectric spark when such light has'been accidentally extinguished; andto attain these ends in a strong, durable, compact, readily assembled,thoroughlyv efficient,A conveniently re-` paired, and comparativelyvinexpensive structure. To Athe above,` ends essentially,Y and to otherswhich may Ahereinafter appear, my invention consists of such parts, andsuch combination of parts whichfall Vwithin the scope of the inventionas claimed. y
